NAME

     gssapi -- Generic Security Service Application Program Interface library

LIBRARY

     GSS-API Library (libgssapi, -lgssapi)

DESCRIPTION

     The Generic Security Service Application Program Interface (GSS-API) pro-
     vides security services to callers in a generic fashion, supportable with
     a range of underlying mechanisms and technologies and hence allowing
     source-level portability of applications to different environments.

LIST OF FUNCTIONS

     These functions constitute the gssapi library, libgssapi.	Declarations
     for these functions may be obtained from the include file gssapi.h.

     New clients/servers will try both the old and new MIC in Heimdal 0.6.  In
     0.7 it will check only if configured and the compatibility code will be
     removed in 0.8.

     Heimdal 0.6 still generates by default the broken GSS-API DES3 mic, this
     will change in 0.7 to generate correct des3 mic.

     To turn on compatibility with older clients and servers, change the
     [gssapi] broken_des3_mic in krb5.conf that contains a list of globbing
     expressions that will be matched against the server name.	To turn off
     generation of the old (incompatible) mic of the MIC use [gssapi]
     correct_des3_mic.

     If a match for a entry is in both [gssapi] correct_des3_mic and [gssapi]
     correct_des3_mic, the later will override.

     This config option modifies behaviour for both clients and servers.

     Example:

	   [gssapi]
		   broken_des3_mic = cvs/*@SU.SE
		   broken_des3_mic = host/*@E.KTH.SE
		   correct_des3_mic = host/*@SU.SE

BUGS

     All of 0.5.x versions of heimdal had broken token delegations in the
     client side, the server side was correct.
